(54) Metal matrix composite structure


(57) The present invention provides a metal matrix composite having stable performance without extremely weak portions and capable of assuring strength with a simple structure, the metal matrix composite being formed by hot-pressing or hot-isostatic-pressing a flat formation of reinforcing fibers (10) sandwiched between metal matrices (12) and comprising a joined end part (11) in the longitudinal direction of reinforcing fibers (10) which is joined obliquely at a joining angle of 5 to 60 degrees with respect to the longitudinal direction of reinforcing fibers or more preferably wherein a plurality of metal matrices (11) and a plurality flat formations of reinforcing fibers (10) are overlapping each other to form layers of metal matrices and flat formations of reinforcing fibers so that the adjacent upper layers of flat formations of reinforcing fibers and the adjacent lower layers of flat formations of reinforcing fibers to a layer having a joined part of flat formations of reinforcing fibers are continuous and have no joined parts.
